Politico interviews Jeff Sessions for its “Off Message” podcast about the future of the Republican Party as it has all but officially nominated Donald Trump as its presidential candidate.

Sen. Jefferson Beauregard Sessions III, Donald Trump’s friendly but fierce Alabama ally, has a message for Republicans still queasy about their party’s nominee: Tide’s about to roll over you.

Sessions, a 69-year-old former state attorney general who famously donned the “Make America Great Again” trucker’s cap at a massive rally in Mobile last August, thinks Trump is more a movement than a man. And this sprightly son of country preachers and teachers is on a mission to evangelize maybe-Trumpers like House Speaker Paul Ryan on the Gospel According to Donald – with a sermon on self-preservation.

“I think [Ryan] needs to recognize, on some of these issues, Trump is where the Republicans are and if you’re going to be a Republican leader you should be supportive of that,” Sessions told me during a taping of POLITICO’s “Off Message” podcast in his Senate office last week.

“My advice is to listen and accept the will of the American people, the Republican voters – the Republican Party is the Republican voters,” he added – a pointed reference to Ryan’s suggestion that he, and not the presumptive party nominee, represents authentic conservative values. “Give me a break! A lot of our drift within our party has gotten away from [the will of the voters] … I think the leaders in all parties tend to adjust to reality. They just have to or they won’t remain in office … Already many are sensing it.”
